Abstract
The utility model relates to liquid transmission, in particular to a frequency conversion system for centralized supply of lubricating liquid. The technical scheme adopted by the utility model is that a lubricating liquid pool is respectively connected with an oil pump and a liquid return channel, the oil pump is connected with a workstation through a liquid supply channel, and the workstation is connected with the liquid supply channel. The frequency conversion system is characterized in that the frequency conversion system further comprises a pressure sensor which is connected on the liquid supply channel, the pressure sensor is connected with a frequency converter through a circuit, and the frequency converter is connected with the oil pump for constitution. The frequency conversion system has the advantages that as the pressure sensor is arranged on the liquid supply channel of the frequency conversion system, when the supply quantity of the lubricating liquid is excessively large, the pressure rises; when the supply quantity of the lubricating liquid is too little, the pressure drops; the pressure sensor transmits a pressure change signal to the frequency converter, the frequency converter adjusts the rotational speed of a motor of the oil pump according to the pressure, so as to change the liquid supply quantity of the oil pump and be applicable to the change of type, process and yield.
Description
Technical field
The utility model relates to the transmission of liquid, especially belongs to the frequency conversion system of centralizedly supply Lubricants.
Technical background
Lubricated district concentrates for Lubricants in the prior art, and a general pump will have tens shower nozzles to use at the same time for many enamelling machines or drawbench, because kind, technology and output is different, the demand of Lubricants also is among the change.Because pump adopts metering pump, the supply that therefore can cause Lubricants too much or very little.
Summary of the invention
The purpose of this utility model is to provide a kind of frequency conversion system of centralizedly supply Lubricants, makes the rotating speed of oil pump to change with the size of pressure, thereby changes liquid supply rate, with the change of adapted breed, technology and output.
Technical solution adopted in the utility model is: it is to be connected with time liquid path with oil pump respectively by lubricated liquid pool, oil pump is connected with work station by the feed flow path, work station is connected with time liquid path, it is characterized in that: it also is included on the feed flow path and is connected with pressure transducer, pressure transducer is connected with frequency variator by circuit, frequency variator be connected with oil pump form.
Usefulness of the present utility model is: 1, because the utility model on the feed flow path of Lubricants, is equipped with pressure transducer, when the supply of Lubricants was too many, pressure can raise; When the supply of Lubricants very little the time, pressure can descend; Pressure transducer can be transferred to frequency variator to the variable signal of this pressure, and frequency variator is according to the large and small motor speed of adjusting oil pump of pressure, thus the liquid supply rate of change oil pump, with the change of adapted breed, technology and output.2, the supply oil pump of Lubricants, after installing pressure transducer and frequency variator additional, the Lubricants supply and the demand that make adapt, and have saved the energy.
